Atomically thin materials such as graphene and monolayer transition metal dichalcogenides
(TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality …

We have experimentally determined the energies of the ground and first four excited
excitonic states of the fundamental optical transition in monolayer WS 2, a model system for …

Transition metal dichalcogenide (TMDC) monolayers have recently emerged as an
important class of two-dimensional semiconductors with potential for electronic and …

We show that the light-matter interaction in monolayer WSe 2 is strongly enhanced when the
incoming electromagnetic wave is in resonance with the energy of the exciton states of …

We demonstrate the formation of large sheets of layered organic-inorganic perovskite
(OIPC) crystals, as thin as a single unit cell, prepared by mechanical exfoliation. The …

Recent studies of the optical properties of 2D materials have reported unique phenomena
and features that are absent in conventional bulk semiconductors. Many of these interesting …

The quasiparticle band structure and optical properties of single-walled zigzag and armchair
SiC nanotubes (SiC-NTs) as well as a single SiC sheet are investigated by ab initio many …

Exciton dynamics, lifetimes, and scattering are directly related to the exciton dispersion or
band structure. Here, we present a general theory for exciton band structure within both ab …

We perform first-principles GW plus Bethe-Salpeter equation calculations to investigate the
photophysics of monolayer hexagonal boron nitride (h-BN), revealing excitons with novel k …

We combine linear and nonlinear optical spectroscopy at 4 K with ab initio calculations to
study the electronic bandstructure of MoSe 2 monolayers. In one-photon photoluminescence …
